Serum levels of IL-4 and IFN-γ. Cytokines in serum were determined by ELISA after 24 h of P. aeruginosa infection. IL-4 was lower in OVA/Bud mice than in OVA/No mice (*P<0.01). IL-4 in OVA/Bud/P.a mice was higher than in OVA/P.a mice (#P<0.01). IFN-γ in OVA/Bud mice was not significantly different from that of OVA/No mice (**P>0.05). IFN-γ in OVA/Bud/P.a mice was not significantly different from that of OVA/P.a mice (##P>0.05). IL-4 in PBS control mice was lower than in all other mice (OVA/No, OVA/Bud and OVA/Bud/P.a). IFN-γ in OVA/No, OVA/Bud, and OVA/Bud/P.a mice was lower than in PBS control mice (P<0.01).
